“More than 200 pages of photos and eyewitness accounts released by prosecutors Thursday show Zimmerman and Martin were in a loud and bloody fight in the moments leading up to the shooting and that Zimmerman appeared to be getting the worst of it, with wounds both to his face and the back of his head,” the Associated Press wrote early Friday morning.

The AP does note Zimmerman could be liable for allegedly approaching Martin, and quotes the family attorney.

“Bleeding tenderness to his nose, and a small laceration to the back of his head. All injuries have minor bleeding,” paramedic Michael Brandy wrote about Zimmerman’s injuries in the report.

Still, the pictures and the evidence show the neighborhood watch volunteer with a bloody nose on the night of the fight. And a paramedic report says Zimmerman had a 1-inch laceration on his head and forehead abrasion.

“Bleeding tenderness to his nose, and a small laceration to the back of his head. All injuries have minor bleeding,” paramedic Michael Brandy wrote about Zimmerman’s injuries in the report.

But even as the pictures shed light on Zimmerman’s injuries, there’s still much that’s in the dark. For example, the release of evidence did little to clear up whose voice is screaming for help in the background of several 911 calls made during the fight.

Since first hearing the calls in early March, Martin’s mother, Sybrina Fulton, has been unequivocal in saying it was her son’s voice on the tapes.

But Serino wrote in a report that he played a 911 call for Martin’s father, Tracy, in which the screams are heard multiple times.

“I asked Mr. Martin if the voice calling for help was that of his son,” the officer wrote. “Mr. Martin, clearly emotionally impacted by the recording, quietly responded `no.’”

Zimmerman’s father also told investigators that it was his son yelling for help on March 19.

“That is absolutely positively George Zimmerman,” Robert Zimmerman said. “He was not just yelling, he sounded like he was screaming for his life.”

Investigators sent all the recordings to the FBI for analysis. They were asked to determine who was screaming, and also if Zimmerman might have used an expletive in describing Martin. Prosecutors said in their charging documents that Zimmerman said “(expletive) punks” in describing Martin as he walked in the neighborhood.

But the analyst who examined the recordings determined the sound quality is too poor to decipher what Zimmerman uttered. In regards to the screams during the altercation, there also wasn’t enough clarity to determine who it is “due to extreme stress and unsuitable audio quality.”
